HYDRAULXG SWlV EL.

Application led August 3,

all whom z't may concern:

Be it known that we, MAHLoN E. LiiYNi; und SAMUEL N. HALL, citizens of the United States, residing at Houston, in the county oiY Harris und State of Texas, lieve invented u new und useful Improvement yin Ilyilruulic Swivels, of which the following is :i specili- 'l cation.

T his invention relates to new and useful improvements in hydraulic swivels.

:The object of the invention is to provide certain improvements over the swivel shown in Letters Patent No. 992,363 issue Muy 16th? 1911, issued to M. E. Layne, N. Hall, and C. F. Layne, said imi iovenient-s consisting of an adjustable pinzhing gland so arranged is to be adjusted from the egiierimof the swivel Without removing :my of the parts thereof; the provision el cone bezirings; the provision of :i l'olloiw-,r ringv {n.l:i;'ted to compensate `for unci en adjustmentoi' the packing gland; provision lor sin oil liuth .about the packing gland; iii-mision for ver-- tically supplying :t lubr einy to the one bearings; provision for locking the nearing collar und the heed in lixed relation; und the provision for temporarily locking the beziring dish' and the heed together lo permit the shell to be unscrewed.

Further objects are r'fi'inxpsictiui-ss., ,simplieA ity of purts, added strength rind, durability, und the reduction of weer to :i minimum.

With the above and other objects iii new, the invention has relation to ceiiiin novel features of construction unil op Miou, un exemple described in this siirciiciilien und illustrated in the ziecomlmzivving rlniv herein:

is a longitudii'uil sectional view portion the beung is :in elevation, ii porA to show the means ii'nr supplying the lubricant to hearing. Fig. 2S is e detail ol" the gland :idiusting means, :ind Fig. Ll is a transverse section on the line .zr-zr of Eig. l. n

In the drawingsi the numeral l designates u head or upper swivel member inning :it its upper end :i loop 2 adapted to receive the usual snpporting hook :ind in orileitto preN vent the disengagement ol' this hookl from the loop during the vertical -rlibriition `ot these parts, u recess 3 is proviiledjit the lower portion ol the loop to receive the lower bend of the hook.

The head is provided at its centrul nortion Figure l of the swivel, with u in elevation. Fig. 2

with :i laterally projecting neck l, in which :i coupling member 5 is rotritably held by a suitable packing member (3. The outer end of the coupling member is screw threaded to reeel ve the hose'conneetion. A passage 7 eX- tenils through thc heed establishing communication with the coupling member; while at the lower end of the passage :i sleeve 8 is sri-ew threaded into the heed :is shown in l ig. l. The lower end of the head is externally screw threaded to receive a, bearing enllzir di which is held in fixed relation with the head by n lateral pin 10 passed through the colhir unil engaged in the hemd iis shown in Fig. 1.

'l ie movable or .rotating section of the L-.iiiicl commises tivo mein ports, :i shell 1l rind. :i coupling nioinberlb:\th cylindrical in "erin. The shell n: liiteil ,snugly about the ali irii'i its lower portion; while its upper noi-i ion is siiiliiriently onlin-'geil to inolose the iiz'ing ci `ler 9. lfhe shell is externally serciv thi fidel :it its upper rndv to receive a ii-.it hearing disk .13, between the underside nl' whiili und the heuring coller t? cone bezirogs '-l ere interposed`r suitiible races being formed in the ilisli; and collar, At its center the toller is formed finnulfir inlder l5. which takes the inward :Thrust of the bearings.

"fie-.i dii-:lq i3 is locked agsiiiistturning inilcgciifleiitly of the shell by n set screw 16 u agli the shell into one of u plut ses 17 in the threaded surface of the dish. After the shell und disk have heini mijnen-d, the serew is driven in und the pur-tn leifltefl. ltk obvious that the shell und dish bolli being free to rotate it would be ililieult to unscrcw the,shell from the dink unless time Ineens ifor holding the disk in lifted relation ywais provided. To ell'eot this :i boss ld, us shown in Fig. i., is formed one side nl the head so :is to project over the disk. This boss is provided with :i hole 19 adapted to register with e. recess 20 in the disk. so thut a pin or the like inserted ink these openings will lock the disk and houd together :and permit the shell to be un screwed. At the intersection of the boss und the head.. :in oil pessiige 21. leads down the with :in up'stunding` sol outer side of the head so as to discharge into the cavity about the bearings, at a point just above the shoulder 15. This passage being formed in the head and being disposed vertically, an oil bath may be maintained about the bearings la and a lubricant supplied through the port 2l at any time and while the swivel is 1n operation, if necessary.

As before stated the shell at its lower p0rtion is fitted snugly about the sleeve 8; however, a suitable packing 22 is inserted from the lower end of the shell between the shell and sleeve. The lower portion of the shell is somewhat contracted and provided with an interior annular shoulder on which horizontal curved bosses 23 are formed in opposed relation. These bosses are at they bottom of the enlarged portion of the shell and form a support for the bearing collar 9. As shown in Fig. l outwardly flaring recesses 24 are formed between the bosses terminating in elongated slots 25 in the shell on each Side, the shoulder of the shell forming the bottom of the recesses. This provision is made for the adjustment of a packing gland 26 embracing the sleeve and adapted to compressthe packing 22 when drawn upward. In carrying out this portion of the invention, the object is to provide for the adjustment of the packing gland 26 from the outside of the shell and without unscrewing or removing any of the parts. lVith their heads disposed in the recesses 24, bolts 2T are passed down through the shell, one diametrically opposite the othei'. The heads of the bolts are shouldered, said shouldered portion of each fitting into a packing box 28 in the base of the recess 24. The lower threaded ends of the bolts extend below the shell and are screwed .into a follower ring 29 encircling the sleeve 8, the inner periphery of the ring rounded transversely to permit the ring to rock and tilt out of a horizontal plane and compensate for an uneven adjustment of the bolts 27. On opposite sides and at right angles to the bolts, rounded lugs 3l) extending up from the ring, as shown in Fig. 3, are seated in the lower edge of the gland 26, constituting a fulcr'um on which the ring is tilted. It is obviousthat by ti htening up the bolts 27, the ring 29, will "e drawn toward the she'll, thereby forcing the packing into the stulliing box thus formed. By reason of the slots 25 and recesses 24, a suitable fiat rigid jaw wrench ma be inserted through the slots alternatelv an engaged with the bolt heads and the ad justing of the packing gland carried out from the exterior of the shell and without disturbing any ot' the other parts of the swivel. Sullicient space about the heads of the bolts is provided to permit a free movel .ment and application of the wrench.

lt is to be observed that while the features Vest described are exuosed the eckin gland and ring are inclosed and protected from foreign matter especially in view of the construction which will be described.

The lower end of the shell is shouldered and screw threaded to receive the annular coupling member 12 reduced at its lower end and externally screw threaded at that point to receive the drill pipe. The member l2 is shaped to provide an annular chamber about the ring 29 and packing gland 26 in which a bath of oil is maintained by introducing the same through a port 33 in the side of the member, which port is normally closed by a screw plug 34. About the sleeve d in the lower end of the coupling member l2 a packing 35 is disposed and compressed by a flanged follower 36 screw threaded into the member about the sleeve.

It is apparent that a very compact and substantial swivel is provided, there being no thin walls or delicate parts. Further the bearings are well protected and eiliciently lubricated and at the same time the construction is such as to remove any chance of the lluid leaking into the partstlie oil. escaping, or foreign matter lodging between working parts.
